在自动纤维铺放（AFP）过程中产生的沉积缺陷降低了生产率，并造成了不合格零件的浪费。这个问题可以通过在沉积过程中实时识别和反应这些缺陷来缓解。为了证明这一概念，本研究增加了AFP过程与轮廓传感器和软件控制。提供了机器、其传感器和控制系统的描述。在实验中，引入了代表典型AFP铺层的两级代表性粘合缺陷。这些缺陷由轮廓传感器检测，当缺陷到达压区点时，机器自动调整工艺参数。显微镜显示，这样的程序可以影响材料的微观结构，并减少在最终固化层压板的面内波纹。这证明了AFP中的“思考-反应”概念的可行性，并为复合材料制造中的实时缺陷监测和纠正迈出了又一步。
Deposition defects arising during automated fibre placement (AFP) reduces production rate and creates wastage from rejected parts. This issue can be alleviated by identifying and reacting to those defects in real-time during deposition. To demonstrate the concept, this study augmented an AFP process with profilometry sensors and software control. Description of the machine, its sensors, and the control system is provided. In the experiment, representative bonding defects at the tow level representative of a typical AFP layup were introduced. These defects were picked up by the profilometry sensors, and the machine automatically adjusted the process parameters when the defects reached the nip point. Microscopy revealed that such a procedure can influence the material microstructure and reduce in-plane waviness in the final cured laminate. This demonstrates the feasibility of the observe-think-react concept in AFP and provides another step toward real-time defect monitoring and correction in composites manufacturing.
